Note that it is possible to break the cluster networking if flags are improperly used and as such this option should be used with caution.
### Configuring Weave NPC EXTRA_ARGS
Weave-npc (the Weave network policy controller) allows you to customize arguments of the running binary by setting the EXTRA_ARGS environmental variable.
This can be used for debugging or for customizing the logging level of weave npc.
```
spec:
networking:
weave:
npcExtraArgs: "--log-level=info"
```
Note that it is possible to break the cluster networking if flags are improperly used and as such this option should be used with caution.
### Configuring Weave network encryption
The Weave network encryption is configurable by creating a weave network secret password.
